The basement can be used by the owners as a storehouse, workshop, laundry and even home. Ventilation in the basement is required to ensure a normal microclimate, eliminate dampness and mold. If the basement is located in the basement, it will be enough to equip the windows or windows in the basement as natural ventilation even at the stage of building construction. This move will facilitate operation and provide normal natural ventilation of the basement.
As a rule, there are no windows in the basements, and their walls are the concrete foundation of the house. Often, residents neglect the waterproofing of the basement walls, which leads to increased humidity. Not insulated walls quickly enough begin to be covered with droplets of condensate, mold. High humidity will significantly degrade the performance of the room. How to make proper ventilation in the basement?
Do-it-yourself natural ventilation in the basement
First you need to measure the area of the basement. For owners of basements with an area of not more than 5 square meters, a simplified basement ventilation scheme is suitable, you just need to drill vents at the base of the building. You need to make at least two holes in the opposite walls directly above the ground. Their diameter is about 10 cm. To enhance the movement of air, a pipe 15 centimeters in length should be attached to one outlet and directed upward or made an outlet 15 centimeters higher if the height of the cap allows.
If the area of the basement is very small, one ventilation pipe will be sufficient. It is divided by a partition to improve air circulation. It’s quite possible to do this part of the basement ventilation with your own hands: vents are drilled with a perforator. The holes of a perforator punch holes in a circle, after which the middle is hollowed out.
Basement Ventilation
For an extensive basement, not separated by partitions, you need a more complex ventilation scheme for the basement: you will have to arrange two ventilation ducts, placing them on different sides.
The mines are equipped with plastic pipes with a diameter of 100 mm. The supply ventilation entrance is located 20 cm above the floor, and the exit is in the basement on the street. The exit should be done vertically, after proper ventilation is made in the basement, an umbrella and a grate are put on the pipe exit. Some owners leave it horizontal, but the grille is required, as well as a damper for the cold season.
The output shaft is mounted 10 cm from the ceiling and goes outside. The height of the pipe is 2.5 - 3 meters. The pipe can be led into the ventilation shaft of the house or through the ceiling in the attic.
Do not always bring the capabilities of the basement ventilation equipment with their own hands suitable for owners. In this case, you can equip the forced ventilation in the basement.
